Wing-In-Ground Effect (WIG) “Flying Sub”

WIGSubIcon

My students asked about the prop-less submarine propulsion system, so I explained the origin of its design as a flying submersible for maintenance of the floating power grid. Continue reading

Evolving Gas at Depth

ElectrolysisIcon

Under test, decomposition of water into oxyhydrogen gas (or HHO gas) yielded a slightly higher efficiency at greater pressure than in open atmospheric pressures. More testing is needed to identify the exact cause of this variation. Continue reading

Plumbing the Depths

I asked the STEMulate Learning workshop participants to create a pressure vessel for our ROV cameras as inexpensively as possible. The current design overall should be less than the per-ROV cost for our Sea Perch designs. Continue reading

February 2014 STEM Workshops

Electronics for a 3DR RepRap printer

February was a busy time with progress made on ROV designs and camera modules, 3DR RepRap 3D printers, and preparations for Workshops and Summer Camps including the Texas A&M University AggieSTEM program! Continue reading

ROV Simulators and Pressure Issues

Illuminated OpenROV Model

Our students continue work on their ROV video monitors using small automotive backup safety cameras and security video cameras protected during submergence by pressure vessels each group is creating by hand. One issue that has emerged from the depth tests … Continue reading

DIY Low-cost ROV underwater Video Cameras

ROV Video Cam ICON

We are continuing to build ROV video feeds using inexpensive ($15 ea) video cameras for our Sea Perch and OpenROV underwater robot designs. Continue reading

The 2014 #SciFund Challenge

#SciFund Challenge Logo

We are crowd-funding additional equipment for our Summer ROV program, trying to obtain an open-source OpenROV and underwater camera to record our student’s explorations through the #SciFund Challenge! Continue reading Continue reading Continue reading

Building ROV Video Monitors from Car Parts

Our participants are building SeaPerch ROV video monitors from inexpensive car components and looking forward to our #SciFund Challenge crowd-funding effort to obtain a deeper-water ROV and camera for this Summer’s programs. Continue reading

Underwater Remote Operated Vehicles (ROVs)

Open ROV 3D Prints

The theme for 2014’s STEMulate Learning workshops will be Robotics and we have much ahead this year with underwater ROVs and a Crowdfunding effort to bring new learning tools that educators can build for themselves! Continue reading
